2.At the first sight the planet Mars does not appear very welcome to any kind of life.It has very little oxygen and water,the temperature at night is below-50~Cand winds of 100 miles per hour cause severe dust storms.However,the surface of the planet seems to show that water flowed across it some time in the past,and it is believed that there is enough ice at the poles to cover the planet with water if it melts.Although there is no life on the Mars now,some scientists think that there may have been some form of life long time ago.At that time,the planet had active volcanoes;the atmosphere was thicker and warmer;and there was water.In fact,in some ways the Mars may have been similar to the Earth,where life exists. Some people believe that the Mars could support life in the future if the right conditions were produced.The first step would be to warm the planet using certain gases which trap the Sun's heat in the planet's atmosphere.With warmth,water and carbon dioxide(二氧化碳),simple plants could begin to grow.These plants could slowly make the Mars more suitable for living.It is estimated that the whole process might take between 100,000 and 200,000 years.In the meantime,people could begin to live on the planet in special closed environments.They would provide a lot of useful information about conditions on the Mars and the problems connected with living there.There could be life on the Mars in the future ifA.it supported life in the past B.certain gases are used to cool the planet C.the atmosphere can be heated enough to grow simple plants D.the planet's volcanoes become as active as they were in the past

    Some scientists think there may have been life on the Mars in the past because__.

    A.there is no life there now
    B.there is a large amount of water at the poles
    C.the Mars may be able to support life in the future
    D.conditions may have been similar to those on the Earth

    答案:D
    解析:
    第一段大意是:人们最初对火星的印象是火星上不可能有生命。因为几乎没有氧气和水,并且夜间温度低于-50°C,同时还有每小时l00英里的风速引起的严重的沙尘暴。然而星球的表面却告诉我们,过去的某个时段水曾经从这里流过。人们相信极地有足够的冰,一旦融化便可覆盖整个星球。虽然现在火星上没有生命,但在过去很久很久以前,生命很有可能存在过。由此可看出,生命所需的条件——水和氧——在火星上和在地球上是相似的。所以选项D正确。而选项B说火星上有水是不对的。火星的极地有冰,只有当冰融化后才能使整个星球有水。

    A Record-Breaking Rover
    NASA's Mars rover Opportunity has boldly gone where no rover has gone before—at least in terms of distance. Since arriving on the Red Planet in 2004,Opportunity has traveled 25 .01 miles,more than any other wheeled vehicle has on another world.
    “This is so remarkable considering Opportunity was intended to drive about 1 kilometer and was never designed for distance,”says John Callas,the Mars Exploration Rover Project Manager.
    He works at NASA's Jet Propulsion Laboratory in Pasadena,California.“But what is really importantly is not how many miles the rover has racked up,but how much exploration and discovery we have accomplished over that distance.”
    The solar-powered Opportunity and its twin rover,Spirit,landed on Mars 10 years ago on a mission expected to last 3 months. The objective of the rovers was to help scientists learn more about the planet and to search for signs of life,such as the possible presence of water.
    Spirit stopped communicating with Earth in March 2010,a few months after it got stuck in a sand pit. But Opportunity has continued to collect and analyze Martian soil and rocks.
    During its mission,Opportunity has captured,and sent back to Earth,some 187,000 panoramic and microscopic images of Mars with its cameras. It has also provided scientists with data on the planet's atmosphere,soil,rocks,aid terrain.
    The rover doesn't seem to be ready to stop just yet. If Opportunity can continue on,it will reach another major investigation site when its odometer hits 26.2 miles. Opportunity has beer working on Mars since January 2004.
    Researchers believe that clay minerals exposed near Marathon Valley could hold clues to Mars's ancient environment. Opportunity's continuing travels will also help researchers as the, plan for an eventual human mission to the Red Planet.

    Opportunity is a record breaking rover in the sense of________.
    A: how long is has stayed in space
    B: how far it has traveled
    C: how much investment it has involved
    D: how many facilities it has been equipped with

    答案:B
    解析:
    根据第一段“NASA's Mars rover Opportunity has boldly gone where no rover has gone before—at least in terms of distance.”可知,“机遇号”比任何漫游车行驶的距离都长。故选B。


    从第二、三段可知,“机遇号”并不是为长途行驶而设计的,它本来预定只能行驶大约一千米。因此“机遇号”在被设计时,约翰并没有准确地知道它的价值。故本题选 B。


    由第四段“The objective of the rovers was to help scientists learn more about the planet and to search for signs of life , such as the possible presence of water.”可知,把“机遇号”和 “勇气号”送上火星的目的之一是寻找生命的迹象。故本题选D。


    根据文章最后两段可知,如果“机遇号”继续行驶的话,在它行驶到26.2英里的时候,它就会到达另一个重要的研究场地——马拉松谷,因此C项正确。倒数第二段第一句说,“机遇号”不会止步于此,故A项错误。B、D项文中并未提到。


    由最后一段可知,“机遇号”接下来的工作能够帮助研究人员实施人类最终登陆火星的计划。故B项“科学家正努力把更多的人类送上火星”是正确答案。

    问答题
    Is There Life on Mars?  The American space agency, NASA (the National Aeronautics and Space Administration), has drawn up a short list of ten research projects that will form the basic of an ambitious program to explore the planet Mars in a mission scheduled for launch in 2007. Scientists are being asked to use their ingenuity to devise novel ways to explore the red planet using intelligent robots and probes that might perhaps answer the biggest question of all—-is there life on Mars?  NASA chose the ten projects from a list of 43 hopefuls. It has included missions for returning samples of Martian dust and gas to Earth, networks of small landers, orbiting constellations of microprobes and a rover that would try to date the precise age of rocks and soils. The ten concepts are part of the Mars Scout program to be launched in six years. This follows a decade of the most intensive interest in Mars since the two Viking probes of 1976 which sent back eerie images of the Martian landscape some 400 million kilometers away.  But the history of Mars exploration is littered with failure—more than half of the 30 missions to date have ended in fiasco. It was NASA’s announcement in August 1996 of possible signs of life  in a Martian meteorite which had fallen to Earth that rekindled intense interest in Earth’s nearest neighbor. It was assumed that liquid water had once flowed on Mars and an ancient atmosphere might have supported living organisms. However, opposing camps of scientists bitterly disputed NASA’s evidence for primitive life-forms in the Martian meteorite ALH84001. This led to the conclusion that the only way of finding out whether life ever existed on Mars is to go there and have a look.  NASA planned a bold series of increasingly complex missions involving the launch of a couple of space probes every year for a dozen years. One of the most successful so far was the shoe-box-sized So-journer rover which thrilled a world Internet audience when it was wheeled out in 1997. Since then, however, NASA has suffered a series of setbacks.  In September 1999 its Mars Climate Orbiter was lost as a failed rocket bum plunged it into the Martian atmosphere. NASA blamed it on one of its team using imperial units and another using metric. Three months later, NASA lost contact with its Polar Lander as it approached touchdown on the frozen South Pole of the planet. Space commentators muttered darkly about Mars being a cosmic equivalent of the Bermuda triangle.  The year of 2001 saw the successful completion of the Global Surveyor mission, an orbiting probe that took pictures of what some scientists say are channels in the dust where water may still occasionally flow from underground well. More recently, the Mars Odyssey probe was launched without hitch and is due to arrive in 2008.  Meanwhile, the European Space Agency is planning its own visit to the red planet with the launch of its Mars Express mission scheduled for take-off in .June 2003. Britain is designated to take a lead role in the project with the Beagle 2 Lander, a small craft, the size of a kitchen sink designed to shuffle over the Martian landscape taking soil and rock samples, analyzing them for signs of life and transmitting the data back to Earth. Beagle 2—framed after the ship that carded Charles Darwin on his voyage of discovery—will weigh just 60 kilograms and will cost about US $225,000 to build, a fraction of the cost of building the Viking space probes more than 25 years ago.  Beagle 2 will look for water, minerals and organic matter. Although it will reach Mars before NASA’s Scout mission is even launched, it will be considerably less sophisticated in tea’ms of analytical technology. The focus now for NASA is on what instruments and robots to put on the Mars Scout mission in six years. Ed Weiler, NASA’s associate administrator for space science, had to decide on a top ten to concentrate NASA’s limited resources.  Each project is to receive a grant of $150,000 to see them through the next six months of development. It all has to come out of a total project budget capped at $300 million. These Scout concepts embody the spirit I first thought about more than a year ago; and will enable us to explore the diversity of Mars in new ways, Dr Weiler said.

    火星上有生物吗? 美国航天机构——国家航空航天局(NASA)已制定出一个包括10个研究项目的简表,这些研究是针对一项雄心勃勃的计划而制定的,该计划将在2007年的一次发射任务中对火星进行探测。科学家们纷纷发挥他们的创造性,寻求新思路,利用智能机器人和探测器来探索这颗红色的行星。“火星上有生物吗?”我们也许能给这个首要问题找到答案。
    美国国家航空及太空总署从43个可行计划中挑选出这10个项目。其中包括:将火星尘埃和气体的样品带回地球,建立小型登陆器网,将微型探测器卫星群送入轨道,以及建造一台能精确确认岩石和土壤年份的探测车。这10个“创新项目”是今后六年将开展的“火星探测计划”的组成部分。1976年,两只“海盗”探测器发回了距地球4亿公里以外火星景观的怪异图像,自此,人们就对火星产生了浓厚的兴趣。“火星探测计划”是这十年来浓厚兴趣的延续。
    然而,火星探测的历史也经历了重重的失败。迄今为止,30多次的探测有一多半均以失败告终。1996年8月,美国国家航空及太空总署宣布,落到地球上的火星陨石中可能存在生命迹象,这一发现重新燃起了人们对火层——这颗离地球最近的星球一的浓厚兴趣。人们推断火星上也曾流淌过河流,远古的大气下可能也曾有生命体的存在。然而,反对阵营的科学家们很不认同火星陨石ALH84001中存在初级生物的证据。因此,要想知道火星上是否存在过生物,唯一的办法就是到那里去看一下。
    美国国家航空及太空总署大胆出台了一系列日益复杂的计划,包括连续12年每年发射几个太空探测器。“寄居者”探测器是迄今为止最为成功的尝试,它只有一个鞋盒大小。它于1997年的面世震惊了全世界的互联网观众。但是从那以后,美国国家航空及太空总署就遭遇了一系列的挫折。
    1999年9月,由于运载火箭出现事故,火星气候轨道探测器在燃烧后消失在火星的大气层中。美国国家航空及太空总署将这次事故归咎于使用了英制和公制两种不同的单位。三个月后,美国国家航空及太空总署又与其在冰冻的火星南极着陆的“极地登陆者”号探测器失去了联系。当时,太空评论员们丧气地评价说:“火星简直就是宇宙中的百慕大。”
    2001年,“星球探测者”号探测器成功完成了使命。它在沿轨道飞行的过程中拍下了一些照片。一些科学家们称他们从中看到了干涸的水渠,地下的泉水也许依然在流淌。较近时候,“火星流浪者”号探测器成功发射,并将于2008年抵达火星。
    与此同时,欧洲航天局也在筹划着对火星的访问。按日程安排,“火星特快”号探测器将于2003年6月发射。英国推出“猎犬2号”登陆器,从而占据了领先地位。“猎犬2号”是一种小型飞船,大概有厨房洗涤槽大小。它可以在火星表面移动,搜集土壤和岩石标本,分析其中的生命迹象并将分析资料发回地球。“猎犬2号”是以查尔斯·达尔文曾经乘坐过的考察船而命名,它的重量只有60千克,制造费用约为22.5万美元,与25年前的“海盗”太空探测器相比,只占其成本的很小一部分。
    “猎犬2号”将在火星上寻找水、矿物和有机物。尽管它将在美国国家航空及太空总署发射“观察者”号之前就到达火星,但就分析技术而言,它还不够精密。美国国家航空及太空总署目前的工作重心是:在六年内确定要把哪些仪器和机器人装载到“火星观察者”号上。为能够集中利用总署的有限资源,美国国家航空及太空总署中主管太空科学的副局长埃德·韦勒只得将注意力集中到以上提到的10个研究项目上。
    每个项目将会得到l5万美元的资助,确保其在今后六个月的开发。未来项目总额预计会达到3亿美元。韦勒博士说,“‘观察者号’的这些构想体现了我一年多以前的理念,它们将为我们提供新的方式来探测火星的多变情况。”

    由第四段“The objective of the rovers was to help scientists learn more about the planet and to search for signs of life , such as the possible presence of water.”可知,把“机遇号”和 “勇气号”送上火星的目的之一是寻找生命的迹象。故本题选D。


    根据文章最后两段可知,如果“机遇号”继续行驶的话,在它行驶到26.2英里的时候,它就会到达另一个重要的研究场地——马拉松谷,因此C项正确。倒数第二段第一句说,“机遇号”不会止步于此,故A项错误。B、D项文中并未提到。


    由最后一段可知,“机遇号”接下来的工作能够帮助研究人员实施人类最终登陆火星的计划。故B项“科学家正努力把更多的人类送上火星”是正确答案。

    Which of the following best summarizes the findings reported in the text about the effects of food deprivation on monkeys’ behavior?
    A

    Food deprivation has no effect on aggression among monkeys.

    B

    Food deprivation increases aggression among monkeys because one of the most potent stimuli for eliciting aggression is the competition for incentives.

    C

    Food deprivation may increase long-term aggression among monkeys in a laboratory setting, but it produces only temporary increase among monkeys in the wild.

    D

    Food deprivation may temporarily increase aggression among monkeys, but it also leads to a decrease in conflict.


    正确答案: D
    解析:
    推导题。文章第二段最后两句提到Southwick’s on the reduction of space or the withholding of food failed to produce more than temporary, increases, in intragroup aggression. Indeed, food deprivation not only failed to increase aggression but in some cases actually resulted in decreased frequencies of aggression,即食物的减少会产生“more than temporary, increases, in hatragroup aggression”,但在某些情况下“resulted in decreased frequencies of aggression”,D项temporarily与原文的temporary对应,decrease与原文的decreased frequencies相对,故D项符合原文意思,为正确答案。

    问答题
    1)The original insight that people could be classified into Type A and Type B personalities and that Type A’s were more heart-attack prone1 grew out of research at the Framingham Heart Study laboratories in the late 1970s.  Dr. Peter Wilson, director of the Framingham laboratories, agreed in a telephone interview last week that since the early studies, the AB issue has been getting weaker. 2)A large prospective study2 (in which people are followed for years before years before they get sick) last year showed the A-B behavior distinction was not associated with coronary artery disease.Now researchers are thinking in terms of “anger in” vs. “anger out” as the latest area of concern.  Behavioral epidemiologist Elaine Eaker at the National Heart, Lung and Blood Institute in Bethesda, one of the nation’s foremost scholars of correlations between behavior and heart disease, agrees in principle.  “There is no epidemiological evidence on hostility alone, but anger has been linked to CHD (coronary heart disease) events weakly for white collar men and more strongly for women in clerical jobs,” she said last week.  “The Type A concept is still viable because it has been a predictor of heart disease in at least two long-term studies. But recent research has shown that how you cope with anger may be the new coronary prone behavior of the future. And it’s tough to cope with anger,” she added.  3)Since holding anger inside may lead to heart trouble and since acting it out by having temper tantrums is highly antisocial, Eaker says researchers now advocate maturely “discussing” anger—either with the person who makes you angry or with a friend—as the most constructive method of dealing with explosive feelings.  4)Since the early Type A studies, researchers have been attempting to fine-tune the ways in which they can identify a person as Type A or Type B, not an easy task since people often deny or are actually unaware of some facets of their personalities and hence can not be asked point-blank if they are angry or impatient by nature .  Dimsdale used both pencil-and-paper questionnaires and a “semi-structured” interview technique to identify Type A personalities among heart patients.  In the interviews, he explained, “you ask questions slowly and sometimes even in a stammer and then see how rapidly the person will finish the sentence for you.” People who rush to answer are usually highly impatient and impatience has long been considered a major component of Type A behavior.  5)Yet, no matter whether he used the self-report questionnaires or the more subtle interview technique, people identified as The A’s did not fare worse than the others.

    正确答案:
    (1)【答案】人类可划分为A型和B型性格以及A型性格的人更易患心脏病——这一独特见解是70年代末期弗拉明汉心脏研究实验室的研究结果。
    【解析】本句是一个主从复合句。句中包含两个that引导的同位语从句以说明insight的内容,且两个从句由and连接。翻译同位语从句时,当从句内容较长时,可先将其解释的内容翻译出来,之后补充要说明的对象。“be classified into”表示“被分为…”,“grow out”指“产生”。prone“有…倾向的,易于…的”。
    (2)【答案】去年的一项大规模前瞻性研究(其间对很多人患病前观察数年)表明,A-B型的行为差异与冠心病没有什么联系。
    【解析】本句是一个主从复合句,括号里的内容做定语修饰“study”,本句谓语是showed,宾语是that引导的从句“the A-B…artery disease”且省略that。宾语从句是被动语态,翻译时将其处理为主动语态以符合汉语习惯。“be associated with”表示“与…相关联”。prospective“预期的,展望的”。
    (3)【答案】既然生闷气可引起心脏病,而靠发泄一通来消气又很可能产生不良社会效果,埃克说,现在研究人员提倡把“恼怒”说出来,平心静气地(或者同惹你生气的人,或者同一位朋友)进行“讨论”。这可以作为对付暴躁脾气的最积极的办法。
    【解析】本句句子很长,但结构较为简单。and连接两个since引导的原因状语从句。破折号中间是插入语说明“discussing” anger的对象。本句宾语较长,可采用拆句法,即先将method的内容翻译出来,之后再说明这是一种好的方法。“either…or”表示“或者…或者”。“lead to”意思是“导致”,“deal with”表示“解决,对付”。antisocial“不擅社交的,非社交的”
    (4)【答案】自从早期的A型性格研究以来,研究人员一直试图改进他们鉴别某人为A型或B型性格的方式,但这并不是一件轻松的事,因为人们常常断然否认或者实际上并没有意识到他们性格上的某些方面,因而不宜直截了当地问他们是否天生爱生气或者急躁。
    【解析】本句是一个主从复合句。首先是since引导的时间状语从句,接着是主句,主句中包含in which引导的定语从句修饰ways,最后一部分是对主句的补充说明,其中该部分是since连接的表示因果关系的句子。翻译定语从句时可将其前置位于修饰的名词之前。 “if…or”连接在asked后面表示“是否”。fine-tune“进行微调,调整”,point-blank“直截了当的”。
    (5)【答案】然而,无论他使用要病人自己填写调查表的方法,还是采取更微妙的面谈技巧,被鉴定为A型性格的人的情况并不比其他人糟糕。
    【解析】“no matter…interview technique”做状语,过去分词短语“identified…”作定语修饰people。questionnaire“调查表”。
